SerialGear USB Adapter for Rover

[Cuziwanano]

Does anyone know the exact model number for the SerialGear adapter that works with Trane comm4 ?
I need to replace my Rover hardware kit and do not need to pay out the wazoo, or add to my collection of converters that do not work.

Any other suggestions such as B&B would be appreciated as well.

This is the one I use. I even mad up a cable to p-lug into the thermostats.

The trane thermostats have a jack for the communication. If you run the wires you can plug into the jack and get on the comm bus for the vav boxes. The jack is an RJ22 jack and the middle 2 contacts are used.
